The substrate transfer device 11 is configured by a belt conveyor and a positioning device. The substrate transport apparatus 11 sequentially transports the substrates 90 in the transport direction and positions the substrates 90 at predetermined positions in the machine. The board transfer device 11 carries the board 90 out of the component mounting machine 3 after the mounting process is completed.

The component supply device 12 supplies components to be mounted on the substrate 90. The component supply device 12 includes a feeder 122 set in a plurality of slots 121. The feeder 122 feeds and moves a carrier tape containing a large number of parts so that the parts can be collected. Further, the component supply device 12 supplies, for example, relatively large components in a state of being arranged on a tray 125 placed on the pallet 124. The storage device 123 of the component supply device 12 stores a plurality of pallets 124 and draws out a predetermined pallet 124 according to the mounting process to supply the components.

The component transfer device 13 transfers the component supplied by the component supply device 12 to a predetermined mounting position on the substrate 90 carried into the apparatus by the substrate transfer device 11. The head driving device 131 of the component transfer device 13 moves the moving table 132 in the horizontal direction (X-axis direction and Y-axis direction) by the linear motion mechanism. The mounting head 20 is fixed to the movable table 132 in a replaceable manner by a clamp member (not shown). The mounting head 20 is one of the constituent devices that constitute the component mounting machine 3. The mounting head 20 collects components and adjusts the vertical position and angle of the components to mount them on the substrate 90. The configuration of the mounting head 20 will be described later.

The component camera 14 and the substrate camera 15 are digital imaging devices having an imaging device such as a CMOS. The component camera 14 and the board camera 15 capture an image based on the control signal and send out image data acquired by the image capture. The component camera 14 is configured to be able to image the component held by the suction nozzle 25 of the mounting head 20 from below. The substrate camera 15 is configured to be able to image the substrate 90 from above.

The component mounting machine 3 configured as described above executes a mounting process for mounting a component on the substrate 90. In the mounting process, the component mounting machine 3 sends a control signal to the component transfer device 13 based on information output from various sensors provided and a result of image processing and a control program stored in advance. Thereby, the position and angle of the plurality of suction nozzles 25 supported by the mounting head 20 are controlled.

4). Configuration of Mounting Head 20 As shown in FIG. 3, the mounting head 20 has a head body 21 that is clamped to a moving table 132 of the component transfer device 13. The head main body 21 is provided with a nozzle tool 22, a tool driving device 23, and an air supply device 24. The nozzle tool 22 holds a plurality of suction nozzles 25 at equal intervals in the circumferential direction on a circumference concentric with the R axis so as to be slidable in the Z axis direction and rotatable around the θ axis. The mounting head 20 includes a type in which the nozzle tool 22 can be attached and detached and a type in which the nozzle tool 22 is fixed integrally. The θ axis is the rotation axis of the suction nozzle 25 that is parallel to the R axis and passes through the axis of each suction nozzle 25.

The tool driving device 23 is constituted by a servo motor, a speed reduction device, a linear motion mechanism, and the like, determines an angle around the θ axis of the suction nozzle 25 and positions in the Z-axis direction. The tool driving device 23 includes an R-axis driving unit 231, a θ-axis driving unit 232, and a Z-axis driving unit 233. The R-axis drive unit 231 rotates the nozzle tool 22 around the R axis with respect to the head main body 21. The θ-axis drive unit 232 rotates each of the plurality of suction nozzles 25 about the θ-axis. The Z-axis drive unit 233 raises and lowers one of the plurality of suction nozzles 25 that is indexed to a specified position in the head body 21 in the Z-axis direction.

The air supply device 24 supplies negative pressure air or positive pressure air generated by an air pump (not shown) to the suction nozzle 25 through an air flow path formed inside the mounting head 20. The air supply device 24 includes a negative pressure channel 241, a positive pressure channel 242, and a valve 243. The negative pressure channel 241 is an air channel used when negative pressure air is supplied to the suction nozzle 25. The positive pressure channel 242 is an air channel used when supplying positive pressure air to the suction nozzle 25.

The valve 243 is operated by, for example, a stepping motor (not shown), and switches between supply of negative pressure air, supply of positive pressure air, and cutoff in the air flow path. When negative pressure air is supplied from the air supply device 24 by switching the valve 243, the suction nozzle 25 sucks and holds the component at the tip. Further, when the suction nozzle 25 is supplied with positive pressure air from the air supply device 24 by switching the valve 243, the suction nozzle 25 releases the part that has been sucked at the tip.

5). Configuration of Inspection System 30 As shown in FIG. 1, the inspection system 30 includes a component apparatus quality determination server (hereinafter simply referred to as “server”) 40, a head bench 50, and a terminal device 60. The server 40 is communicably connected to the head bench 50 and the terminal device 60 via the Internet. In the present embodiment, the head bench 50 is not connected to the terminal device 60 so as to be directly communicable. The server 40 performs a predetermined inspection according to the operator's operation on the head bench 50 or the terminal device 60 and causes the terminal device 60 to display a pass / fail determination result of the mounting head 20 based on the inspection result.

In this embodiment, the server 40 is a cloud server, and is connected to a plurality of clients (for example, a plurality of head benches 50 and a plurality of terminal devices 60) in a communicable manner. Here, the head bench 50 is an inspection apparatus that performs an inspection by operating the mounting head 20 according to the type of inspection for the mounting head 20 constituting the component mounting machine 3.

The head bench 50 is mounted with the mounting head 20 by a clamp mechanism and holds the mounting head 20 in an operable manner. The head bench 50 can operate the tool driving device 23 of the mounting head 20 to be held, and can circulate air or the like through the air flow path of the air supply device 24. As shown in FIG. 4, the head bench 50 includes an inspection unit 51 and a control device 52. The inspection unit 51 performs various inspections on the mounting head 20 using a dedicated sensor or camera.

In this embodiment, the inspection by the inspection unit 51 includes an inspection of the mechanical accuracy of the mounting head 20. The above “inspection of mechanical accuracy” is an inspection of whether or not the drive unit (R-axis drive unit 231, θ-axis drive unit 232, Z-axis drive unit 233) of the mounting head 20 operates mechanically accurately. The inspection unit 51 measures, for example, the rotation angle of the inspection nozzle by rotating the inspection nozzle attached to the mounting head 20 around the θ axis and then rotating it backward. Thereby, the backlash in the θ-axis drive unit 232 is detected. Further, by measuring the position of the inspection nozzle before and after the driving of the Z-axis drive unit 233, the inclination of the holder that holds the suction nozzle 25 is detected.

Also, the inspection by the inspection unit 51 includes an inspection of the operation time of the drive unit (R-axis drive unit 231, θ-axis drive unit 232, Z-axis drive unit 233) of the mounting head 20. In the “operation time check” described above, the drive unit of the mounting head 20 is instructed to perform a specified operation, and the time required for the operation is measured. The operation time of the drive unit varies with the drive load depending on whether the drive unit is properly lubricated or the degree of contamination. The inspection unit 51 moves, for example, a predetermined distance with respect to the drive unit of the mounting head 20 or rotates it by a predetermined angle, and measures the pulse power supplied to the servo motor. The operating time and driving load of the driving unit of the mounting head 20 are detected according to the amount of pulse power.

Also, the inspection by the inspection unit 51 includes an inspection of the operation waveform of the servo axis provided in the mounting head 20. The above “inspection of operation waveform” is performed when the drive unit (R-axis drive unit 231, θ-axis drive unit 232, Z-axis drive unit 233) of the mounting head 20 uses a servo motor as a drive source. The drive unit is instructed to perform a specified operation, and the output pulse (operation waveform) of the encoder incorporated in the servo motor is measured during the operation. In the servo motor, the output pulse fluctuates with respect to the same operation according to the degree of deterioration of components and contamination. Therefore, the inspection unit 51 detects the position detected by the encoder and the waveform of the output pulse that converges in the specified operation.

In addition, the inspection unit 51 supplies negative pressure air or positive pressure air to the air flow path of the mounting head 20 and measures the air flow rate in the negative pressure flow path 241 and the positive pressure flow path 242 by a flow rate measurement sensor (not shown). . In the inspection process, the inspection unit 51 rotates the nozzle tool 22 around the R axis in a state where negative pressure air or positive pressure air is circulated, rotates the holder holding the suction nozzle 25 around the θ axis, or Z The flow rate in various states is measured by moving it up and down in the axial direction. When the flow rate in the air flow path of the mounting head 20 is lowered, it is assumed that the air flow path is dirty or the lubricity of the movable part is lowered.

The control device 52 is a controller mainly composed of a CPU, various memories, and a control circuit. The control device 52 is communicably connected to the server 40. The control device 52 controls the operation of the mounting head 20 and various sensors so that a predetermined type of inspection designated by the server 40 is performed. In addition, the control device 52 acquires an identification code (ID) stored in the mounting head 20 by communicating with the mounting head 20.

Further, the control device 52 operates the mounting head 20 according to the type of inspection as described above, acquires measurement values necessary for subsequent pass / fail judgment, and generates inspection data M1. The measurement values of the inspection data M1 may include values measured by various sensors such as the position and angle of the nozzle, the required time of the movable part, the pulse power, the air flow rate, and the pressure. Further, the inspection data M1 can include image data used to determine the position and angle of the nozzle and the like.

Furthermore, the inspection data M1 may be data according to the inspection instead of or in addition to the above measurement values. Specifically, when inspecting the inclination of the holder that supports the suction nozzle 25, the control device 52 determines the inclination angle of the holder based on the measured value indicating the position of the inspection nozzle before and after raising and lowering. Then, the control device 52 may record the tilt angle in the inspection data M1.

In addition, the headbench 50 only acquires the measurement value or calculates the data according to the inspection in any of the various inspections, and does not perform the pass / fail judgment using the measurement value or the like, or identify the malfunctioning portion. . For this reason, the head bench 50 does not store important information such as determination reference data necessary for determination of pass / fail in various tests.

The terminal device 60 is a display device that displays various types of information. The terminal device 60 also functions as a guidance device that performs adjustment guidance for the mounting head 20. In the present embodiment, the terminal device 60 includes a touch screen 61 as shown in FIG. The touch screen 61 displays various types of information and accepts operations by the operator. The terminal device 60 is communicably connected to the server 40. Further, the terminal device 60 receives the result of the pass / fail determination and the information related to the adjustment guidance from the server 40 and displays the information on the touch screen 61. The terminal device 60 is given a unique identification code (ID), and sends the identification code to the server 40 as necessary.

The terminal device 60 displays on the touch screen 61 such that the type of maintenance processing for the mounting head 20 set on the head bench 50 can be selected, for example. The “maintenance process” includes various inspections for the mounting head 20 which is one of the component devices of the component mounting machine 3, and adjustment guidance based on the inspection results. Then, when a predetermined type of maintenance process is selected by an operation on the touch screen 61, the terminal device 60 sends the type of maintenance process to the server 40.

The server 40 functions as a constituent device pass / fail judgment server by installed software. As shown in FIG. 1, the server 40 includes a processing control unit 41, an inspection data acquisition unit 42, a determination unit 43, a transmission unit 44, an access restriction unit 45, an adjustment unit 46, a log recording unit 47, and a storage device 48. . The process control unit 41 controls the operation of each unit in the maintenance process, and acquires an identification code (ID) of the external device through communication. The inspection data acquisition unit 42 acquires inspection data M1 obtained by a predetermined type of inspection by the head bench 50. The inspection data acquisition unit 42 stores the acquired inspection data M1 in the storage device 48.

Here, the storage device 48 is configured by an optical drive device such as a hard disk device or a flash memory. In the storage device 48, in addition to the inspection data M1, the determination reference data M2 and the adjustment reference data M3 are stored in advance. The above “determination reference data M2” corresponds to the range of the inspection data M1 that the normal mounting head 20 shows in the inspection by the head bench 50. That is, the determination reference data M2 includes a range and a threshold for the mounting head 20 to be inspected to be normal in the inspection item based on the inspection data M1.

Also, in the “adjustment reference data M3”, the adjustment location and the adjustment amount in the mounting head 20 corresponding to the inspection data M1 are set. In other words, in the adjustment reference data M3, a position to be adjusted is specified in the mounting head 20 constituted by a large number of parts corresponding to a plurality of measurement values included in the inspection data M1, and the adjustment to the adjustment position is performed. Information capable of calculating the amount is set in advance. The determination reference data M2 and the adjustment reference data M3 are important data that are set based on many achievements and tests and should be prevented from flowing out to the outside.

The determination unit 43 determines pass / fail of the mounting head 20 based on the acquired inspection data M1, and stores the pass / fail determination result in the storage device 48. The determination unit 43 determines the quality of the mounting head 20 based on the inspection data M1 and the determination reference data M2. That is, the determination unit 43 determines that the mounting head 20 is normal when, for example, the measurement value included in the inspection data M1 is included in the normal range indicated by the determination reference data M2.

In addition, the determination unit 43 determines the degree of pass / fail in the pass / fail determination based on, for example, whether the measured value is near the center of the normal range, near the boundary, or far from the normal range. . The determination unit 43 stores the degree of pass / fail in the inspection item in the storage device 48 in association with the pass / fail determination result.

The transmission unit 44 transmits the pass / fail determination result determined by the determination unit 43 to the terminal device 60 that is communicably connected via the Internet. In addition, the transmission unit 44 transmits adjustment guidance information indicating the adjustment location specified by the adjustment unit 46 described later and the calculated adjustment amount to the terminal device 60. The terminal device 60 receives the pass / fail judgment result and the adjustment guidance information and displays them on the touch screen 61.

The access restriction unit 45 restricts access from the terminal device 60 to the determination reference data M2 or the adjustment reference data M3. Specifically, for example, when the terminal device 60 is connected to the server 40 so as to be communicable, the access restriction unit 45 is accessible by specifying a client device using the identification code or the IP address of the terminal device 60. Restrict information. The access restriction unit 45 allows the determination reference data M2 and the adjustment reference data M3 to be updated for access from a device having management authority.

Also, the access restriction unit 45 may restrict accessible information by user authentication instead of or in addition to the above method. The access restriction unit 45 restricts access to the determination reference data M2 and the adjustment reference data M3 from a client device that does not have management authority, regardless of which method allows communication with the terminal device 60. Thereby, the transmission unit 44 does not transmit the inspection data M1, the determination reference data M2, and the adjustment reference data M3 to the terminal device 60.

The adjustment unit 46 specifies the adjustment point of the mounting head 20 and calculates the adjustment amount based on the inspection data M1 and the adjustment reference data M3. Specifically, the adjustment unit 46 determines the quality of the inspection items calculated by the determination unit 43 based on the inspection data M1, for example, when the mounting head 20 is determined to be defective in the quality determination by the determination unit 43, and Based on the adjustment reference data M3, the adjustment location relating to the inspection item is specified and the adjustment amount is calculated. The adjustment unit 46 stores the adjusted adjustment information indicating the specified adjustment location and the calculated adjustment amount in the storage device 48.

The log recording unit 47 records a trace log M4 that enables the inspection and adjustment guidance to be traced when the server 40 determines whether the mounting head 20 is good or bad. The “trace log M4” includes an operation history of the mounting head 20 in the inspection. In the present embodiment, as shown in FIG. 5, the log recording unit 47 includes the identification code (ID) of the mounting head 20, the inspection data M 1, and the identification information (ID) of the terminal device 60 in the operation history of the mounting head 20. At least one is associated and recorded as a trace log M4.

The trace log M4 indicates, for example, a command signal for the mounting head 20, a control signal for the tool driving device 23 and the air supply device 24 in the mounting head 20, and the mounting head 20 when the inspection system 30 performs a predetermined inspection or adjustment guidance. Operation completion notification information and the like are recorded as operation history along with time. The log recording unit 47 further records, as a trace log M4, a communication record between the server 40 and the head bench 50, a communication record between the server 40 and the terminal device 60, an operator operation record on the head bench 50 or the terminal device 60, and the like. Also good.

6). Maintenance Processing Using Inspection System 30 Maintenance processing using the inspection system 30 will be described with reference to FIG. The mounting head 20 to be subjected to the maintenance process is assumed to be, for example, one that has been operating for a certain amount of time since the previous maintenance process or one that has been repaired such as part replacement. In the maintenance process, for example, the head bench 50 is transported to the installation location of the component mounting machine 3 or the mounting head 20 is transported to the installation location of the head bench 50.

When the mounting head 20 is set on the head bench 50 and the start of the maintenance process is requested from the terminal device 60, the server 40 executes the maintenance process as shown in FIG. Note that a plurality of servers 40 may be operated corresponding to countries, regions, and the like. In this case, among the plurality of servers 40, for example, the one having the smallest communication load is selected from the installation location of the head bench 50, and the maintenance process is executed.

The process control unit 41 of the server 40 first acquires the identification code of the terminal device 60 that requested the start of the maintenance process (S11). Next, the process control unit 41 acquires the identification code of the head bench 50 on which the mounting head 20 designated as the processing target is set and the identification code of the designated mounting head 20 (S12). Thereby, the process control unit 41 confirms whether communication with the head bench 50 is possible. In addition, the process control unit 41 may interrupt the maintenance process when it is determined that the maintenance process execution request is not from an authorized user based on the identification codes acquired in S11 and S12.

Subsequently, the process control unit 41 designates the type of inspection according to the request from the terminal device 60 and instructs the head bench 50 to execute the type of inspection (S13). More specifically, the process control unit 41 determines that an inspection of mechanical accuracy and an operation time of the drive unit of the mounting head 20 are necessary in accordance with the maintenance process selected by the operator in the terminal device 60. The head bench 50 is instructed to perform each inspection. Thus, the type of inspection commanded to be executed to the head bench 50 varies depending on the type of maintenance processing selected.

The head bench 50 performs one or more types of designated inspections (S14). The control device 52 of the head bench 50 generates inspection data M1. The inspection data acquisition unit 42 acquires inspection data M1 obtained by a predetermined type of inspection by the head bench 50 (S15) and stores it in the storage device 48. The determination unit 43 determines pass / fail of the mounting head 20 based on the acquired inspection data M1 and determination reference data M2 (S16).

Subsequently, the transmission unit 44 transmits the pass / fail determination result determined by the determination unit 43 in S16 to the terminal device 60 via the Internet (S17). The terminal device 60 displays the received pass / fail judgment result on the touch screen 61 (S18). Accordingly, the operator can determine whether or not it is appropriate to use the mounting head 20 for the mounting process based on the quality determination result of the mounting head 20.

It should be noted that the terminal device 60 displays the determination result about the quality of the mounting head 20 in the selected maintenance process, while not displaying the result of the predetermined type of inspection performed by the head bench 50 according to the maintenance process. The maintenance process includes an inspection mode in which only the above inspection is performed and an adjustment mode in which adjustment is performed using the inspection result. The process control unit 41 determines whether or not the adjustment mode is selected for the maintenance process in the terminal device 60 (S21).

When the adjustment mode is selected (S21: Yes), the adjustment unit 46 specifies the adjustment point of the mounting head 20 and calculates the adjustment amount based on the inspection data M1 and the adjustment reference data M3 (S22). And stored in the storage device 48 as adjustment guidance information. Subsequently, the transmission unit 44 transmits the adjustment guide information generated by the adjustment unit 46 in S22 to the terminal device 60 via the Internet (S23). The terminal device 60 displays the received adjustment guidance information on the touch screen 61 (S24). As a result, the operator can recognize which part of the mounting head 20 is to be adjusted and how much adjustment should be made based on the adjustment guide information.

On the other hand, when the inspection mode is selected for the maintenance process (S21: No), the process related to the adjustment (S22-S24) is omitted. Thereafter, the log recording unit 47 records the identification code of the mounting head 20, the inspection data M1, and the identification information of the terminal device 60 as a trace log M4 in association with the operation history of the mounting head 20 (S25). Furthermore, the log recording unit 47 records a communication record between the server 40 and the external device (head bench 50, terminal device 60) and an operation record for the external device as a trace log M4.

7). Access Restriction Processing for Server 40 The access restriction processing by the access restriction unit 45 will be described with reference to FIG. The access restriction unit 45 executes an access restriction process as shown in FIG. 7 when there is access to various data from an external device. Here, the external device includes client devices such as the head bench 50 and the terminal device 60. The client device includes a management device having management authority.

The access restriction unit 45 first identifies the access authority of the accessed external device (S31). The access authority is specified by specifying a client device using an identification code of an external device or by user authentication. Next, the access restriction unit 45 determines whether to allow access to data with the access authority specified in S31 (S32). When permitting access to the data (S32: Yes), the access restriction unit 45 allows the external device to output or update the data (S33).

On the other hand, when the access restriction unit 45 does not permit access to the data (S32: No), the access restriction unit 45 restricts access to the data with respect to the external device (S34). Specifically, for example, when the external device is the head bench 50 or the terminal device 60 and the data requested to be accessed is the determination reference data M2 or the adjustment reference data M3, the access restriction unit 45 sets the data Restrict access to, and do not send to external devices.

8). Effect of Configuration of Embodiment The server 40 according to the present embodiment connects the Internet to the head bench 50 that operates the mounting head 20 according to the type of inspection for the mounting head 20 that constitutes the component mounting machine 3. It is the server connected so that communication is possible via it. The server 40 designates a predetermined type of inspection on the head bench 50, acquires the inspection data M1 obtained by the inspection by the head bench 50, and the mounting head 20 based on the acquired inspection data M1. The determination part 43 which determines quality is provided, and the transmission part 44 which transmits the quality determination result which the determination part 43 determined to the terminal device 60 connected so that communication was possible via the internet.

According to such a configuration, the server 40 in the inspection system 30 is configured as a separate device connected via the Internet to the head bench 50 that performs the inspection and the terminal device 60 that displays the quality determination result. Thereby, the maintenance process can be performed and the convenience can be improved by transporting the head bench 50 to the installation location of the component mounting machine 3 or transporting the mounting head 20 to the installation location of the head bench 50. On the other hand, since the pass / fail judgment is performed by the server 40, the head bench 50 and the terminal device 60 are separated from important information for inspection such as the judgment reference data M2. Therefore, it is possible to reliably prevent such information from leaking and improve the manageability of the maintenance process for the mounting head 20.

Further, in the case of the inspection system 30 having the configuration illustrated in the embodiment, the server 40 can be accessed from a device having management authority. Therefore, the administrator of the inspection system 30 can aggregate and analyze the results of inspections by a large number of inspection apparatuses (head benches 50), for example. Furthermore, the administrator of the inspection system 30 can update the determination reference data M2 and the adjustment reference data M3 to be more appropriate based on the results of the above analysis. Thereby, in the subsequent maintenance process, the updated determination reference data M2 and adjustment reference data M3 are reflected, and a more appropriate maintenance process can be executed.

9. Variations of Embodiment 9-1. Regarding the inspection apparatus In the embodiment, the inspection system 30 includes a head bench 50 as an inspection apparatus. On the other hand, in addition to the head bench 50, the inspection apparatus may adopt a mode in which the inspection apparatus is incorporated in a substrate working machine that performs a substrate work using a component device. For example, the inspection apparatus may be incorporated in the component mounting machine 3 and inspect the mounting head 20 based on image data acquired by imaging by the component camera 14.

According to such a configuration, the inspection device of the component mounting machine 3 causes the mounting head 20 to perform a predetermined operation, and images the state before and after the operation with the component camera 14 or the like. Then, the inspection apparatus measures the operation amount and the required time of the mounting head 20 based on the image data acquired by imaging, and generates inspection data M1 as in the embodiment. The server 40 determines pass / fail of the mounting head 20 based on the inspection data M1 and the determination reference data M2.

Here, the component mounting machine 3 may employ a configuration in which the mounting head 20 is inspected using the component camera 14 which is an existing facility, and the inspection result is used for calibrating the operation of the mounting head 20, for example. However, if the component mounting machine 3 is configured to be able to inspect the mounting head 20 as described above, there is a risk that important information for inspection, such as determination reference data, may leak. On the other hand, according to the configuration as described above, since the function of performing the pass / fail determination is separated from the inspection apparatus incorporated in the component mounting machine 3, the manageability of the inspection apparatus in the component mounting machine 3 can be improved. Thereby, an inspection apparatus can be incorporated in the component mounting machine 3, and the convenience of maintenance can be improved. Note that the inspection apparatus may have a configuration in which the function of performing adjustment guidance is omitted.
